Tileset edges creating visual borders when game is converted to 3D

JosephDoubleYou commented 3 months ago

Description

When using camera_set_view_mat and camera_set_proj_mat, the tileset that was previously seamless now has flickering edges at the border of each tile. Gamemaker discord helpers confirmed that this was an issue they had never seen before with tilesets in 3d.

Expected Change

Tiles should be seamless, even when the camera perspective changes to 3d.

Can you add some screenshots that show exactly what you are seeing that you don't expect to see? The enclosed project doesn't show any issues when I run it here. Thanks

Hey, here is a video ref of the issue. That is odd, because I sent a project file to members of the Gamemaker discord, and they confirmed that they saw it as well. I am on a mac, and they confirmed that they were on a pc when they checked.

That looks like you have interpolation on - if you go to Options->macOS->Graphics and deselect Interpolate colours between pixels does this fix it?
